About Polypropylene

 

Polypropylene is the second most widely used polymer in the world. It possesses remarkable properties such as strength, stiffness, and the ability to be made in a variety of molecular weights and crystallinities. Around 30% of the global demand for PP is used, among other things, for packaging applications. Serving sectors (such as automotive, sports equipment, clothing, medical components, etc.) Polypropylene is produced worldwide from the polymerization of propylene gas as a raw material in the presence of a catalyst, which can be Ziegler-Natta or a metallocene catalyst. Depending on the required polymer quality, various polymerization conditions (temperature, pressure and reagent concentrations) are taken into account. The polymerization conditions can include a gas phase process (fluidized bed or stirred reactor) or a liquid phase process (suspension or solution). Most of the PP products are processed by extrusion blow molding, injection molding, and general purpose extrusion processes. The types of PP produced using these processes such as homopolymers, random copolymers, impact copolymers, deep drawing, films, etc. are used for various applications in various downstream industries.
